There are several ways to commit your firmware, or bootloader to NAND. These methods can update your Didj with a fresh firmware, or a modified one with proper packaging.

''' Caution ''' Make sure your batteries are charged, or you have an A/C adapter. Also that you understand, there is a certain level of risk making these modifications. Make sure you read through it first, and understand what is being done, before proceeding. Its best to first test these methods with a known working firmware or bootloader. And reading through [[Didj_U-Boot_NAND_Flashing| U-Boot NAND Flashing]] to make sure you can recover if things go wrong.

This update can be done with out a console connection, and mimics how LFConnect handles the task. Both updates can be done at the same time. This is exactly like '''With Built in Tools''' except we trigger the Didj to run those commands for us, by giving our package a higher version number. This is nice if you do not have console access to the device.

* If you keep getting the Tune Up screen after ejecting your device, you'll need to remove firmware-LF_LF1000/ and/or bootstrap-LF_LF1000 from /Didj/Base on the device. As it will keep thinking it needs an update.

Check out [[Didj_SCSI_Commands|SCSI Commands]] for how to use SCSI Commands.

==== Manually ====

+

This method is for the advanced user. You must understand the partition layouts. Copy your file to /Didj/Base and run the following commands:

+

flash_eraseall /dev/mtd0

+

nandwrite -p /dev/mtd0 /Didj/Base/lightning-boot.bin

There are two ways to do trigger the update with the eject command.

If you're on Linux run the sync command, to flush the filesystem buffers.

Then run the SCSI Command C6 "Disconnect Ok", which will cause it to say its "Learning New Tricks" before saying its okay to disconnect your Didj.

''' OpenDidjConnect '''

+

== Update With OpenLFConnect ==

−

This is a program that does the SCSI Commands for you. You just need to give it the action desired, and the drive letter (Windows) or device (Linux).

+

+

Once OpenLFConnect is installed and set up, you can update the firmware and or boot loader by using its specific commands and pointing them at the files to use. This is basically a python script that runs the necessary sg3_utils programs on Windows or Linux.

Mount your Didj and [[Didj_USB_Mounting#Assigning_Drive_Letter| Assign it a Driver Letter]]

+

local>didj_mount

+

... device info ...

−

Prepare your firmware or bootloader folder, just like the ''' SCSI Commands ''' section. But instead of running those commands, use OpenDidjConnect instead.

+

Run firmware update command giving it a path.

+

remote>didj_update_firmware /path/to/firmware-LF_LF1000

+

Didj will upload the firmware, then eject when files have synced.

−

'' On Host ''

+

For bootloader its the same process.

+

local>didj_mount

+

... device info ...

+

remote>didj_update_bootloader /path/to/bootstrap-LF_LF1000

−

$ OpenDidjConnect -d <drive_letter> -c eject

+

Or us just plain didj_update and point it to the parent directory of both.

−

== Caution ==

+

Once the Didj has rebooted after the update.

−

It is possible to cause a major malfunction with your Didj by replacing these files. Familiarize yourself with the procedure using known-good packages first.

+

local>didj_mount

+

... device info ...

+

remote>didj_update_cleanup

−

You should also be familiar with [[Didj_UART_Boot| Didj UART Boot]] before using these procedures. The UART boot allows non-destructive testing of bootloaders and firmware/kernels; it also provides a recovery method in case a new bootloader or firmware/kernel written to the NAND fails.

+

This will delete the update directories from the Didj, to prevent updates from running every time it is didj_eject is run.

−

When using SCSI commands, check that you are using the correct syntax and that you are sending them to the correct device.

+

== Update With LFConnect ==

+

If you are using Windows, and have LFConnect installed, you may find this way suites your needs. There is no special programs or need to run commands on the device itself.

Summary

There are several ways to commit your firmware, or bootloader to NAND. These methods can update your Didj with a fresh firmware, or a modified one with proper packaging.

Caution Make sure your batteries are charged, or you have an A/C adapter. Also that you understand, there is a certain level of risk making these modifications. Make sure you read through it first, and understand what is being done, before proceeding. Its best to first test these methods with a known working firmware or bootloader. And reading through U-Boot NAND Flashing to make sure you can recover if things go wrong.

Prerequisites

Programs Needed

Software Needed

DIDJ-0x000E0002-000001.lfp (bootloader)

DIDJ-0x000E0003-000001.lfp (firmware)

Update With Console Access

Using Built in Tools

This method will use a few built in programs that come with the Didj for updating the firmware and bootloader. You will need to copy, or create a folder, and certain files in it for this to work It is easiest to extract the folder from the lfp archives and modify it as needed.

Firmware

For firmware this method will install into the opposite partitions, than the one you are on, so if you are on RFS0, the update will be installed to RFS1. And the Didj will be configured to boot from that one.

If you keep getting the Tune Up screen after ejecting your device, you'll need to remove firmware-LF_LF1000/ and/or bootstrap-LF_LF1000 from /Didj/Base on the device. As it will keep thinking it needs an update.

Manually

This method is for the advanced user. You must understand the partition layouts. Copy your file to /Didj/Base and run the following commands:

Update With Out Console Access

Force Update with Custom SCSI Commands

This update can be done with out a console connection, and mimics how LFConnect handles the task. Both updates can be done at the same time. This is exactly like With Built in Tools except we trigger the Didj to run those commands for us, by giving our package a higher version number and telling the Didj to eject. This is nice if you do not have console access to the device.

If you want to do both at the same time, load both folders into /Didj/Base then run the command to eject.

Bootloader

For bootloader create a folder in /Didj/Base called prefixed with 'bootstrap-' (ex. bootstrap-LF_LF1000)

It should have the same files as the lfp package.

Make sure meta.inf has a version number higher than Version="1.35.2.4222" or if you've changed the version number in your file system, higher than that one.

Firmware

For the firmware create a folder in /Didj/Base called firmware-LF_LF1000

It should have the same files as in LFP package DIDJ-0x000E0003-000001

Make sure meta.inf has a version number higher than Version="1.35.2.4222" or if you've changed the version number in your file system, higher than that one.

Trigger Update With SCSI Commands

If you're on Linux run the sync command, to flush the filesystem buffers.

Then run the SCSI Command C6 "Disconnect Ok", which will cause it to say its "Learning New Tricks" before saying its okay to disconnect your Didj.

Then turn the Didj off.

This processes causes the Didj state machine to look for a folder called firmware-LF_LF1000, if its a newer version, which is found in meta.inf and compared to /etc/version on the Didj, it will update the files with the new ones.

Update With OpenLFConnect

Once OpenLFConnect is installed and set up, you can update the firmware and or boot loader by using its specific commands and pointing them at the files to use. This is basically a python script that runs the necessary sg3_utils programs on Windows or Linux.
